ERITISE COMPANY DYE arcenn Application filed July 20, 1831, Serial No.552,059, and in Great Britain March 27, 1931.

This invention relates to dye jiggers, and

has for its object to provide a'simple and reliable arrangement of thedriving means for the driven rollers of the jigger whereby I am enabledto obtain a practically uniform cloth speed between the rollersnotwithstanding their relative diameters due to the amount of cloththereon at any moment. A further object of the invention is to providean improved arrangement of reversing mechanism which does notnecessitate the employment of spring or like loaded devices within thecloth folds on the rollers, which devices are exposed to the dye liquorand may mark the fabric.

The invention comprises the improved combinations and arrangements ofparts hereinafter described and claimed.

Referring to the four accompanying sheets of explanatory drawings Figure1 is an end view,- Figure 2a front view and Figure 3 a rear view of adye jigger having my improved drive applied thereto.

Figures 4 and 5 are detail views of the brake to be hereinafterdescribed.

Figure 6 is a diagrammatic view of the electric control panel and Figure7 is a detail view of the means for determining the automatic stoppingof the machine, this view being taken at right angles to the view of thesimilar parts in Figure 6.

The same reference letters in the diflerent views indicate the same orsimilar parts.

The dye jigger illustrated comprises the two driven rollers a, b and theguide rollers c, d, e within the dye vat f. The rollers 0, d, e areturned by the cloth as it travels between the driven rollers a and b.

The rollers a, b are each driven by a separate direct current electricmotor 9, 7:, through spur gearing e", j.

Upon the shaft of the roller 6 is mounted a worm is which drives a wormwheel m on a shaft n which by means of a worm 0 and worm wheel 3) drivesa disc 9 upon the peripheral edge of which dogs a, 8 are clamped so thatthey can operate an arm 6 to be hereinafter referred to.

'Theshaft of each of the rollers a, 12 carries a one-way clutch, asshown in Figures 4 and 5, for causing the rotation of a brake drum uwith which engages a brake band o anchored at w to the bracket a:supporting a bearing of the roller shaft. The brake pressure is adjustedby the hand wheel 3 When the roller a or b is travellingin the directionwhich pays out or delivers cloth therefrom, the rollers z of the one wayclutch cause the drum u to rotate with the roller shaft sothat the brakeband exerts a definite resistance to the rotation of the shaft, and thusany overrunning of the fabric is prevented.

When the roller a or b is rotating in a direction to wind cloth thereon,the one-way clutch is inoperative as the rollers 2 move clear of thedrum u; the brake has, therefore, no effect upon the rotation of theroller by its motor. 7

The armatures of the two motors a and b are arranged in series in thesupply main, as shown in Figure 6 where the armatures are indicated at 8and 9.

The field windings of the motors indicated at 10 and 11 are in parallelbetween the supply mains.

The connections to the commutator brushes of the armatures are made totwo pairs of terminals 12 13 and 14, 15, and these terminals areconnected to two solenoid or electro-magnetically operated switches 16and 17 the connections to 17 being open connections and the connectionsto 16 being crossed connections, so that if 16 be closed the currentwill flow in one direction through the armatures and if 17 be closed itwill flow in the reverse direction.

The electric mains are indicated by 18 and The switches 16 and 17 arecontrolled by electro-magnetic coils 20 and 21 connected by the lead 22through the lamp 23 which acts as a'resistance to the main 18 and by thetwo leads 24 and 25 with contacts 26, 27 with which can engage a contactblade 28 connected to a lead 29 which is connected by contact blades30,31 with the main 19.

The contact blade 28 would normally engage the contact 26 but it iscontrolled by a cam like part 32 upon the fulcrum of an arm 33 having apointed upper end adapted to be till om. ilS "Ni til plunger 1i 1 L 1. ii.- rowaids the g'agement but they can. be moved. apart by cam upon aspindle upon which two ratchet wheels 42, 4.3 are secured and aboutwhich two pawl carrying arms 4 and 45 telcrum. @ne arm 44; is connectedby a linlr id to arm aand the other arm is connected by a link 4.1? tothe arm 35., The pawls are numhered 48 and respectively, Thisarrangement of two ratchet wheels and two jawls operated from theopposite sides of the fulcrum point of the arm ensures that the shaft-41 is turned through a distance represented by a tooth of the ratchetwheels each time 25' is moved whether to the right or to the litter theratchet wheels have been turned through a certain number of teethdependent upon the initial relationship of the cam 40 to the blade 30,the later is moved clear of 31 and the circuit through the blade 38 andthe coils 20, 941 broken The pointer or finger {Figure 2) indicates theposition of the cam 40 and allows the operator to set the some todetermine the number of times the cloth is passed from a to i) and heel;from to a before the machine is stopped automatically" lVith theimprovement in which two direct current motors 9, it having theirarmatures arr need in series drive the driven rollers (11, l) of themachine, as one roller increases in diameter and becomes heavier due tothe winding of cloth thereon, the motor driving the same tends to slowdown, whil the motor driving the other roller which is becoming lighteras the cloth is removed therefrom, tends to speed up. There is thus anautomatic balancing action between the motors which gives the desireduniformity of cloth speed under all conditions of winding on to andunwinding" from rollers, with a uniform cloth tension between therollers. The simplicity of the arrangement is at once apparent as itdoes not depend upon any mechanical action resulting from changes indiameter of the rollers on to and from which winding is taking place,

The reversing mechanism depends for its actuation upon the position ofthe dogs 7, s upon the disc 9. It s strikes 25 (Figure 2), the latter ismoved to the left and causes through the. plunger 34, the arm 33 to beee -"i one pawl or Wheels L i 1 The ner is engaged, it is by the do tothe The arm e and the coil 5 36 energizes ture circuit is then closedthrough is connection 1%, -6
